Physical properties
Hardness of 6-7 on Mohs scale; composed primarily of quartz, alkali feldspar, and plagioclase; typically pink, white, or gray with a phaneritic (coarse-grained) texture and dull to vitreous luster.
Formation & geological history
Formed from the slow crystallization of magma deep beneath the Earth's crust, commonly associated with continental tectonic plates over millions of years.
Uses & applications
Widely used in construction, architectural buildings, monuments, countertops, and decorative paving stones due to its durability.
Geological facts
Granite is the most common rock of the Earth's continental crust and is exceptionally resistant to weathering.
Field identification & locations
Easily identified in the field by its interlocking, visible mineral grains of quartz, feldspar, and dark micas; found globally in shields and mountain roots.
